Choose your decade, from the 1950's to the 'noughties' and then choose your type of question. You can have 'Who had a hit with?', 'In which year was .... a hit for ......?' or '..... was a hit for ......'. Alternately you can answer on 'Number Ones' for all the decades. You have 10 seconds to answer the question, and you get 25 points for a correct answer. So if you answer correctly after 8.5 seconds, you score 85 for the time, and 25 for a correct answer, so 110 points. You can also test your knowledge of your own music library, by seeing if you can identify the 'intros' before the first 20 seconds have elapsed.
